  1. 1. Acoustic Droplet Vaporization : An Assessment of How Ultrasound Wave Parameters Influence the Vaporization Efficiency

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Sara Öquist; [2020]
    Keywords : Acoustic Droplet Vaporization; Verasonics; Ultrasound; Vaporization Efficiency; Phase-change Contrast Agents;

    Abstract : Acoustic droplet vaporization (ADV) is a process in which a phase shift of a liquified droplet into a gaseous microbubble, is triggered using an ultrasonic wave. In contrast to utilizing conventional contrast agents in ultrasound, the phase change contrast agents used in ADV can extravasate into tumor tissue, and they offer a greater circulatory lifespan, thereby increasing the potential applications in which they can be utilized.

  2. 2. Putting behavioral assays on fish to the test: Are sociality and scototaxis trials relevant in the wild?

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Arno Veenstra; [2020]
    Keywords : Acoustic telemetry; Social network; Sociality; Scototaxis; Migration;

    Abstract : Animal behavior has become a frequently used tool in modern ecology and ecotoxicology, where laboratory behavioral traits are recognized as sensitive endpoints for assessing natural behavior or non-lethal effects of pollutants on animals. Within these research fields, behavioral traits measured in laboratory environments have been used to formulate predictions of ecological consequences that accompany specific behavior. READ MORE

  3. 3. What's Next in Sustainable Acoustic Materials?

    University essay from Lunds universitet/Produktutveckling

    Author : Klas Hellqvist; Anna Andersson; [2020]
    Keywords : Sustainability; Acoustics; Materials; Sound Absorption; Technology and Engineering;

    Abstract : As industries have begun to rethink the way they design, make and dispose of products for the purpose of sustainable development, manufacturers of acoustic products have been slow off the mark. The majority of acoustic products are still made of primarily virgin material made from petrochemical resources, which have a significant impact on the environment. READ MORE

  4. 4. Attenuation AND awareness? : Designing a method for measuring accuracy and certainty of sound identification when wearing a HPD

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Author : Markus Ahlberg; [2020]
    Keywords : Industrial design engineering; method design; sound identification; situational awareness; hearing protection devices; noise pollution; level-dependent function; Teknisk design; metoddesign; ljudidentifikation; situationsmedvetenhet; hörselskydd; buller; bullerföroreningar; nivåberoende funktion;

    Abstract : Noise pollution is widespread in today’s society, from traffic to industrial sources, and many people are confined to unhealthy acoustic environments through their employment. When noise cannot be eliminated at the sound source, the protective measure is usually to equip the employee with hearing protection devices (HPDs), e.g. READ MORE

  5. 5. Do people with larger lungs speak in longer utterances and inhale less frequently? : Relationships between lung capacity, respiratory rate, proportion of lung capacity used for speech and utterance durations

    University essay from Stockholms universitet/Institutionen för lingvistik

    Author : Denise Karlsson; [2020]
    Keywords : Lung capacity; respiratory rate; speech volume; utterance duration;

    Abstract : This study examined the relationship between lung capacity, speech volume and duration of utterances. 8 adult subjects, 4 males and 4 females (24-36 yrs), participated. By breathing into a digital spirometer, lung capacities such as Vital Capacity (VC) and Inspirational Capacity (IC) were estimated. READ MORE
